Hey guys! Hope everything is ok! If you already know me from somewhere or have seen the presentation of Crystal ambassadors, you know that I am very proud to say that I am one of the ambassadors, bringing content about Crystal to the Brazilian technology communities, so on July 23rd (on Sunday) at 2 pm in Brazil (UTC -3) and 5 pm in UTC +0, I will be giving a presentation about Crystal: an introduction to the language and everything it has to offer! [He4rt Developers](https://heartdevs.com/) is the community of developers in Brazil that I love and care about for being a community that welcomed me, making me what I am today, producing educational content that was essential for my professional and personal growth. Today I can say that I already contributed twice with two study guides within the community, with content for the LPI-E1 certification and of course with an incredible guide in Portuguese for an [introduction to Crystal](https://github.com/lanjoni/crystal4noobs), making me finally able to be [part of the ambassadors](https://forum.crystal-lang.org/t/crystal4noobs-the-brazilian-github-repository-for-beginners-with-crystal/5287)! None of this would be possible without the He4rt Developers community. Therefore, as one of the forms of contribution, I will present this content online, at a pleasant time, free of charge for everyone who wants to participate. The content itself will be presented mostly in Portuguese, but soon I intend to make a presentation in English! I’m waiting for you there! Thank you very much! From the community to the community. Da comunidade para a comunidade 💜 🖤 > ---
